Is it possible to detect an usb device when the device is plugged in??

[yonghan]

I want to ask,is it possible to detect a device that are connected to the usb port?And directly link to the software that we've made?Thanks a lot

it is possible. try using Win32_ControllerDevice, Win32_USBHub, Win32_Controller class from WMI Classes. there may be other alternatives that more suitable for your app, but you need to be more specific (eg: is the device a storage device? or custom made hardware, etc). HTH

In a few cases the hardware came with software, which in turn may have an API for you to automate.

Other alternatives are,you could check if the usb device is emulating serial port / network. if it is emulating serial port then you can use System.IO.Ports.SerialPort class. if the device capable of TCP/IP communication then you can use System.Net.Sockets.Socket class. other than that you can use Windows API.

Most customer display device i know emulate serial port (COM5/COM6) perhaps yours too.

Check the software that came with the device, or try the website. When you install the software, sometimes it installs the API with it.
